TPS2001DDGKR

The TPS2001D power-distribution switch is intended for applications where heavycapacitive loads and short circuits are likely to be encountered, such as USB.

The TPS2001D limits the output current to a safe level by operating in a constant-currentmode when the output load exceeds the current limit threshold. This provides a predictable faultcurrent under all conditions. The fast overload response time eases the burden on the main 5-Vsupply to provide regulated power when the output is shorted. The power-switch rise and fall timesare controlled to minimize current surges during turnon and turnoff.
